Elsa is a female given name mostly used in the Scandinavian countries.
In the past, Elsa was simply a short form for the biblical name Elisabeth and some of its variants: Elisabet, Elisabetta and Elizabeth.
The first records mentioning the name Elsa were produced in Sweden in the 15th century and it became a generally used name only after the 19th century.
After the release of Frozen at the end of 2013, the name became more popular in different countries across the world.
In Sweden the name was in the top 10 baby names before Disney's Frozen was released, yet it became the most popular name only afterwards, in 2014 and 2015.
In the US, the number of babies named Elsa was 487 in 2010, and it more than doubled in 2014.
